REVIEWS & RATINGS

I'm petit (5'4'', 105lbs) with a wide shoulder and tiny waist. It fits my shoulder perfectly but is loose around my waist. Even though, it looks good while I'm standing and does look bulky when I'm seated - a bit alteration will make it perfect.
Material is good for spring/summer/early fall.

I am usually a size s. I am tall but petite, I own this jacket in a size 2 and a 4. The 2 is a bit tight across my back and chest and slightly short in the arms. The 4 is a better fit and is definitely not too large for me. The size difference between the 2 and the 4 is minimal, I needed to try them both on a few times to actually tell what the difference was.
Please review what you buy, it really helps everyone with their shopping :)

This blazer has incredible construction. A beautiful piece that will be very versatile. I ordered the 2 and I am normally a "true 2". The blazer was slightly small. I could have gotten away with wearing the 2 but for the price I did not want to settle, so I returned it.

This is the perfect blazer. It fits really well in the shoulders, length of arms, waist, everywhere. And the fabric has just the right amount of give. I can see myself wearing this a lot, so glad that I purchased it!

Ladies, invest in this blazer. In fact, invest in a pair of Theory pants to go with this blazer. You will not regret buying a full Theory suit. The fit of this jacket is extraordinary. It's very slimming and has just a bit of stretch to keep up with your crazy antics without losing it's form. And yes, send this to the dry cleaners. Don't attempt to wash this yourself!

I got this blazer intending on wearing it for work. Thought it was a bit expensive initially, but when it arrived I saw how well tailored it was and it looks waaaay better than a similar department store jacket I got (that on hindsight cost more than it's worth).Fits well and doesn't bunch up in the chest or back area. Good investment.
